Hi,

I've got some problem with S7-1200 webserver LOG-IN.

We made connection betweeen S7-1200 webserver and another webserver (this is simple PC webserver not S7-1200!).

The PC webserver send datas to S7-1200 webserver like this method: PC webserver log-in with admin to S7-1200 webserver, than send datas(write variable in CPU), than log-out.

We can make this method ca. 30-40 reps. (reps are variable), than S7-1200 doesn't allow access anymore.

First time we try that the PC webserver only log-in to S7-1200 webserver (doesn't log-out), than send datas. With this method we can send datas only 6 reps, here's the reason why:

What could be the solution, that we don't need to wait 30 mins., that the session running out!?

Or have Anyone other solutions?

Thanks for advance!
